Tinited States Patent CONTAINER FOR CHEMICALS John C. Parkhurst, Jr., Oklahoma City, Gkla.

Application March 29, 1954, Serial No. 419,473

16 Claims. (Cl. 206-=-47) The present invention relates to a container for packing and shipping chemical components which it is undesirable to mix prior to use because of decreasing potency, generation of heat etc. or because of a corrosive effect or other deleterious effect on the container.

The primary object of the invention is to provide a novel means for separately carrying separate ingredients which, when about to be used, may be mixed within the container. A

An extremely important object of the invention is to provide means for the packing and shipping of corrosive chemicals with the solvent in a conventional container whereby the components will be mixed upon puncturing the container.

A very important object of the invention is to provide a means for suspending one of the components of the container from the undersurface of the lid of the container in a pliable receptacle requiring no modification of conventional container structures.

An important feature of the invention resides in the provision of a puncturable sealing arrangement whereby the means for puncturing the seal mixes the components and additionally provides a seal for agitating the components within the container prior to their use.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to theaccompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the container with parts being broken away to disclose the receptacle mounting structure constituting the present invention;

Figure 2 is a side elevational view of the upper portion of the container with the lid thereof punctured showing the manner in which the components of the container are brought into contact with one another;

Figure 3 is an enlarged detail view of the means for puncturing the lid of the container and releasing one of the components of the container from its receptacle;

Figure 4 is a top view of the blank from which the pliable receptacle mounting means is formed; and

Figure 5 is a perspective view of the blank rolled into its receptacle holding form.

Referring to Figure 1, the numeral designates a receptacle of a conventional nature which may be of any suitable material such as metal. In the form shown, the container is cylindrical and includes a lid 12 closing the top thereof; however, it is obvious that the container could be of many shapes.

Shown within the container is a liquid component 14 which may comprise a suitable solvent or the like.

Secured to the undersurface of the lid 12 is a constricting member in the form of a collar or sleeve 16. Carried by the constricting member 16 is a bag of pliable material containing the second component or ingredient of the container. The bag is designated by the numeral 18 and the component carried thereby may be either liquid or solid materials, the reaction of which with the solvent 14 would corrode or otherwise deleteriously afiect the container 10. As shown, the central portion of the pliable receptacle 18 is restricted by the constricting member 16 so that the bulk of the material within the bag or receptacle is disposed toward the ends of the receptacle on opposite sides of the constricting member giving the receptacle the shape of a dumb-bell.

The lid 12 and sleeve 16 are provided with registering apertures 20 and 22, respectively. The sleeve 16 is provided further with a second aperture 24, diametrically opposite the first aperture 22.

Sealing means, preferably in the form of solder, although other suitable puncturable sealing means are contemplated, close the registering apertures 20 and 22.

To release the component from the bag 18 into the component 14 in the container, puncturing means 28 is provided. As shown, the puncturing means 28 comprises simply a pointed shank 30 formed at the upper end thereof with a grasping head 32. The diameter of the shank 30 is substantially equal to that of the aperture 22 in the sleeve 16. Thus as the shank penetrates the soft, sealing material 26 and projects through the apertures 20, 22 and 24, it automatically forms a seal in the lid 12 to prevent the escape of liquid from the container. The apertures 22 and 24 within the sleeve or collar 16 are substantially equal to the width of this member so that the receptacle 18 will be broken into two sections upon penetration of the shank 30 therethrough. As shown in Figure 2, these sections will then fall into the liquid component 14 within the container whereby the components will mix, the seal formed by the shank 30 enabling the agitation of the container to hasten or complete the mixing of the components.

In this arrangement, conventional metal containers may be used in the packing and shipping of corrosive chemicals in the same container with the solvent; this is particularly advantageous in the shipping of photographic chemicals; however, it is obvious that the invention is not limited to such chemicals.

In the use of the invention, the sleeve 16 is first formed with a flat blank as shown in Figure 4. The blank is formed with a constricted central portion 34 and bulbous end portions 36 forming laterally projecting tabs 38. The central section 34 is formed with a circular section 40 made up of weakened segments. Taking the blank as shown in Figure 4, the same is first soldered or otherwise secured to the undersurface of the lid and placed around the central section of the pliable bag 18. Then the blank is rolled into a collar or sleeve with the end flaps 38 at each end overlapping one another to constrict the central portion of the bag and push the material therein to the opposite end of the bag to form the bag shape shown in Figures 1 and 2. The lower portion of the constricted central portion 34 of the blank 16 forms the bottom aperture 24 in the sleeve and the weakened segments in the central portion form the triangular shaped struck-up tabs 42 as shown in Figure 5 which form the opening 22 in the central portion of the sleeve. These tabs are initially pressed upwardly through the aperture-20 in the lid 12 of the container 10 and outwardly bent to retain the blank on the undersurface of the lid. Then, the solder or other sealing material 26 seals the entrance to the container and the blank is rolled into the sleeve 16 carrying the bag 18, the solder assisting the tabs in retaining the sleeve 16 on the under surface of the lid.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims, a
